Be it known that I, DANIEL S. MARVIN, of Watertown, in the county of Jefferson, .and State of New York, have invented an Improved Knife and Fork-Soourer; and I do hereby declare that thefollowing is aolear, full, and explicitdescription of the construction and operation of the saine, reference being had to the annexed drawings, making a part of .this specification, in 'whiche- Figure 1 is a perspective view,'showing accurately thc whole machine.

The upper bar A carries, in anut, the coarse square thread-screw C, which, when turned, force'lsfthe lower j bar, B, which is movable upon thc upright wires a a, with coil-springs b 6, through each end ofboth bars, down upon the knives, holdingthem upon the knife-board, with the assistance of the three little upright slats Iet'intlo `the edge of the board, and the other eclge of the notch in the adjustable slat C, which is movable at pleasure,

to accommodate large or small knives, by loosening the thumb-screw d, at the endof the adjustable slatC. i

I construct the machine by taking, a convenient board, nailing slats upon three edges, making au excava- Ation long enough'to hold siii knives, the shape of the lower. portion of a knife-handle, inserting three little upright slats in the edge, wide enough apart to hold each two knives, aiiixing the movable slat by a sc rewthroughv purposes set forth.

a mortise at each end, to the vac-ant edge, and a'ixing the two bars over the handles when inserted, by a' strong wire through the ends, bent and driven, one end into the board, the Vother into the upper bar, instead of nuts,` A the upper bar carrying the screw c, to force the lower one down upon the knives, which latter is again raised when the pressureis remo'ved, by two small wi'rc springs, b b, around the large upright wires a a.

-I operate the machine by inserting the knives, in pairs, back -to back, under .the'b'ar, turning down the screw,'and polishing with the cork orosswise of the blades, with a. little dry sand or brick-dust. When one side is polished, raise the bar, place one knife over the other, turning them both over without taking from under the bar, then polishand wipewith a dry cloth without washing. Forks are scoured with the cork,'without beingv inserted in the machine. The knives must all be of the same size or. set. v

What I claim as my invention, and desire to secure by Letters Patent,is- The' oo mbinationo` the adjustable slat C with the bars A and B, rods and coil-'springs b by, a's and for the 'DANIEL s. MARVIN. Witnesses:
